What Is the Borg Rate of Perceived Exertion (RPE) Scale?
The Borg Rate of Perceived Exertion (RPE) scale is a simple, subjective tool that lets individuals rate how hard they feel they are working during physical activity. Developed by Swedish physiologist Gunnar Borg in the 1960s, the original scale ranges from 6 (no exertion) to 20 (maximal exertion), roughly correlating with heart rate (multiply the RPE by 10 to estimate beats per minute). A later 0‑10 version provides a more intuitive range for clinical and recreational use.

Why Professionals Use RPE PDFs
PDF charts of the Borg scale are widely used because they are portable, printable, and can be laminated for gym or clinic walls. They serve as quick references for:
- Personal trainers designing interval sessions
- Physical therapists monitoring patient effort during rehab
- Researchers standardizing exertion levels across study participants
- Athletes self‑regulating intensity without heart‑rate monitors
Key Features of a Good Borg RPE PDF
When selecting a PDF, look for these verified attributes:
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Scale Version | 6‑20 and 0‑10 side‑by‑side | Official Borg publications |
| Visual Clarity | High‑contrast numbers, at least 12 pt font | Peer‑reviewed ergonomics study |
| Durability Recommendation | PDF optimized for 300 dpi printing | Print industry guidelines |
Where to Find Authoritative Borg RPE PDFs
Below is a curated list of reliable sources. All links lead to free, openly accessible PDFs that have been cited in academic literature or endorsed by professional bodies.
- National Strength & Conditioning Association (NSCA) – Provides a printable 6‑20 chart with a brief usage guide.
- American College of Sports Medicine (ACSM) – Offers a dual‑scale PDF (6‑20 & 0‑10) designed for clinical settings.
- University of Copenhagen's Exercise Physiology Department – Hosts a research‑grade PDF with heart‑rate conversion tables.
- PubMed Central (PMC) article supplements – Many peer‑reviewed studies include the exact PDF used in their methods.
How to Verify a PDF's Authenticity
Because the Borg scale is public domain, anyone can create a PDF. Use these steps to ensure you're using a trustworthy version:
Check the Source
Prefer PDFs hosted on .edu, .gov, or recognized professional organization domains. Avoid PDFs from generic file‑sharing sites without attribution.
Cross‑Reference the Scale
Compare the numbers and descriptors against the original Borg publication (Borg, G. (1970). Perceived exertion as an indicator of somatic stress. Scand J Rehabil Med). The descriptors should match:
- 6 – "No exertion at all"
- 9 – "Very light"
- 13 – "Somewhat hard"
- 17 – "Very hard"
- 20 – "Maximum effort"
Look for Licensing Information
Many reputable PDFs include a Creative Commons or public‑domain notice, indicating they are free to distribute.
Practical Tips for Using the Borg Scale in Your Routine
Once you have a reliable PDF, integrate it into your workflow:
- Pre‑workout briefing: Show the chart to participants and ask them to pick a target RPE (e.g., 13 for moderate cardio).
- During exercise: Encourage athletes to glance at the chart every few minutes and adjust intensity accordingly.
- Post‑session log: Record the average RPE alongside heart rate and perceived fatigue for future comparison.
Common Misconceptions About the Borg Scale
Understanding the limits of RPE prevents misuse:
- It's not a precise physiological measurement. RPE reflects perception, which can be influenced by mood, temperature, or caffeine.
- It's not only for elite athletes. The scale is validated for sedentary adults, clinical patients, and youth when age‑appropriate descriptors are used.
- It doesn't replace medical monitoring. For cardiac rehab, RPE should complement, not replace, heart‑rate or blood‑pressure checks.
Frequently Asked Questions
Q: Can I create my own Borg PDF? Yes, but ensure it mirrors the official scale and includes the standard descriptors to remain scientifically valid.
Q: Which version should I use? The 6‑20 version aligns with heart‑rate estimates (RPE × 10 ≈ bpm) and is common in endurance training. The 0‑10 version is preferred in clinical settings for its simplicity.
Q: How often should I update the PDF? Only when design changes are needed (e.g., larger font). The scale itself has remained unchanged since its 1970 validation.
